The present invention includes a control system with a joystick controller for controlling the direction and speed of one or more controlled systems, such as a boom lift platform or the vehicle on which it rides. The joystick is neutrally-biased and effects a null velocity of the controlled system when the joystick is positioned in a neutral position. The joystick controller has motors, or the like, that provide intuitive tactile feedback to the joystick operator. The tactile feedback includes biasing the joystick away from the neutral position according to the controlled system's actual direction and speed but without generating a commanded direction and speed based on the biased position. |
